"rated for" is iffy. In the DIY EVSE world, it's becoming well-known that the standard home depot-grade NEMA 14-50 outlet, although "rated" for 50amps, has a tendency to release the magic smoke.

People suspect the traditional duty cycle used in rating these has been more for dryers, kilns, or welders, where they're active for an hour tops or at least not drawing full current. An EVSE can be at full power much longer, making the rating... less reflective of real-world conditions. I've heard there's a new rating system coming out designed especially for EVSE-sized duty cycles.

And that's not even getting into things like torque specs for the connections, etc.

None of this is blocking a dedicated, well-researched, and properly equipped DIYer, but at this level of power, there's enough "tricks of the trade" involved where the risk-to-reward ratio falls maybe outside the casual "buy things off AliExpress and who cares if the magic smoke comes out" range.

At this current, spending an extra couple hundred bucks might be worth it to have an actual company with a non-made-up-syllables name and a non-Shanghai-alley address that my insurance company can go after if my garage goes up in flames because their UL claims were misleading.

Then, how would it fix things then if it wasn't private equity dominating that market?

There would still be regulations that would allow public equity wheelchair makers to jack prices.
Not to nitpick, but polar flights can (and do, as a back-up, sometimes not only) use HF comms (which do not rely on a line-of-sight, as the waves are long enough to "bounce" off the ionosphere). It's slow (~300bps if transmitting data?), sometimes (but rarely) can have latency up to 15 minutes (interference from the Sun and others stars breaking/jamming comms for some short time, along other phenomenons), but it works. Even 15 years ago not every commercial airplane had satcom link installed, and even now, HF is the only thing which is required when flying away from VHF range. But anyway satcom is just more convenient usually (as long as it is available and it works).

On the other hand, I also think that some *ground* safety systems will rely on satellite data links as a back-up, as well.
I've had the exact opposite experience. Ten years ago I had to go through all sorts of multi-round coding tests, and in my last two jobs it's only been one or just a high level technical discussion.
I think the difference with qualia is that it has so many ethical implications too.

Yeah, swiping is a dark pattern employed by dating apps.

Even with millions of users, there's better ways to match people up than a simple swipe. It's to keep people at the mercy of an algorithm where spending money is the only way to get any sort of control over what you see.

It exists only for shady monetisation.
Intuative for new users is often less efficient for experienced users so for many complex professional tools that will be a core part of the users' work it probably makes sense to go for the less intuative but more efficient tool and provide training.

Note the "core part" though. Even professional tools that many people have to use occasionally (say tools to book professional travel) should be intuative because someone who uses it once or twice a year will forget complex things. But it's probably OK for a CAD program used by engineers as a main part of their job to have a steep learning curve.
You all sound fake.

I can buy an electric wheelchair at Walmart for $750. What is the issue?
Today there is another top post on HN that's like "50 years of PC OSes" and that's the history I think about when I notice how poor and obtuse a lot of modern software is. It's been half a century and still we get totally convoluted and poorly-abstracted interfaces for the software we're either paying good money for, or generating good revenue for the vendor by using. I mean, the reason is obvious - "what's the shortest path to ship something that will do what we (or our users) want, and be profitable?" - but it's disappointing to see almost zero divergence from this apparent inevitability. :\
Structually, it's a tree. JSON cannot include circularity (like JavaScript objects can) so it's either an object, or nested objects.
I have a feeling that if there was not a healthy amount of competition in the space, the prices would start to trend towards the cost of human work.
The first edition was absolutely critical in helping me understand how to program anything more than simple scripts. I got hooked into the physics simulation portion and created a pretty fun Asteroids-inspired game.

Although OOP is going out of style, I think learning it is super important to understand how you can use layers of abstraction to build increasingly complex programs.
Okay, I mean I'm aware of that perfectly generic information but "sometimes management sucks" doesn't impact a feasibility analysis much. And this hypothetical station was already willing to spend on a lot on batteries.
Kind of a tough read, felt a bit like dancing around a point or not quite getting to one. It seems like the author learned how to use a power drill recently then quizzed a random chat on how they work (something he didn't know 5 mins before), then concluded that the UX is not good based on those results. Might be just the wrong audience, both the author and those in the chatroom might not be the target customer of the power drill, and whoever the target customer is might prefer clear numbers on a dial like that - probably because of paradigms set forth in power tools.

I consider it similar to an audio engineer staring at a complex screen of panels, dials, scales - to a random person it wouldn't be intuitive at all, but to the target customer that's exactly how they are surfacing the important parts of their work to a control space.

By the way - the author ultimately did figure out how to use the drill, can't help but wonder if anyone in the chat had to use a drill for some reason, they would simply watch the same video and easily figure it out too - or more likely just turn it, see the difference and be like "Ah ok" without even understanding what torque is.

Article could use an ending or something definitive - this piece wants to be more insightful. Maybe a few more visuals to keep the reader close to the author's train of thought.
They do draw that conclusion - "the lowest point estimate for all cause mortality was approximately 2000 MET min". What their analysis did not identify is what level of exercise beyond that results in a significant increase in mortality risk. If you look at the individual studies that have categories above 2200, (Slattery 1989, Arraiz 1992, Besson 2008, Kvaavik 2010, Paganini-Hill 2011, Brown 2012, Arem 2015, Huerta 2016, Klenk 2016, Celis-Morales 2017, Lear 2017, Zhou 2017, and Liu 2018), there is some variation - almost every study shows a U-shape, but the lowest point differs by gender, age, measurement method, BMI, and so on. And the effects of too much exercise are small compared to the effects of too little, so it is not surprising that their basic univariate analysis with Stata glst is unable to resolve it. But given the number of U-shape studies I think it is reasonable to conclude that some amount is too much - in the absence of reliable statistics I would say to trust one's body and if it feels like you are pushing yourself hard every week then cut back.

I am willing to bet that this change would achieve approximately nothing.

The people who have a mental model that allows them to understand what torque is and how it matters for drilling are the same people who will already know it's controlling torque, specifically torque of the head, controlled by a clutch mechanism. Nothing else makes sense.

And therein lies the problem of believing "good UI will solve everything". It will not give you an understanding of the problem domain. And an understanding of the problem domain will obviate many UI needs.
If the car batteries can handle some amount of power, batteries on the other side can handle the same amount.

Especially because the station would want to have multiple cars worth of energy stored, which means the load is divided among more cells and they don't have to work nearly as hard.
Ease of recording has made remote bands and collaborations very common, you can trade stems with people anywhere and make music.

This would be a million times more useful without the geographical restriction, although I concede if the true intent is to make in person bands then sure, it's useful. Just consider the wider market.
If the Electrical Engineers were included in this layoff I would be surprised. But as you say, they failed to meet the 800v goal, so they probably deserve it too.
> In free market it's also OK to cut costs as much as possible, making chair that explode and kill the user one day after the warranty expires.

No, it isn't, because nobody will buy chairs from a company that does that. In a free market, no company can use the get out of jail free card of "but I was following all the regulations". Businesses have to actually meet customer needs.

And in a free market, customers can't delude themselves that Big Brother is looking out for them (even though Big Brother is not actually doing that); they know that they have to enforce quality if that's what they want. That means customers know that it's on them to be savvy enough to be able to evaluate the quality of products and services.

> That's why we have regulation: to establish the minimum standards.

That's what regulators claim, but all history shows that claim to be wrong. The end result of regulations is to reduce the quality and availability of products, not increase them. The wheelchair market described in the article is a classic example: it's regulated up one side and down the other, yet customers can't get simple things like proper footrests.

> Simple medical devices like wheelchairs (Class I or Class II) are also not super over-regulated, you don't need to do clinical trials to certify them.

Doesn't this contradict your claim that regulation is the only way to avoid exploding chairs? If you don't do clinical trials, how do you know the chairs won't explode one day after the warranty expires?

Of course the answer to this is that the regulators just, you know, look at the design of the chairs to evaluate them for certification. But customers could do the same thing for themselves, at less cost (what, you think those government regulators work for free?). So the regulations are actually adding zero value. But they're certainly not adding zero cost.

> All-in-all it'll cost you around $10m, which is not at all a moat.

So you'll be going into the wheelchair business then? Looks like there's plenty of opportunity to out-compete the current incumbents.
Often the drum pattern that best fits into a song is simple/boring. Maybe stereotypically, it's hard for the drummer to resist "overdoing" the drums.

I think there's a metaphor that can be applied to software engineers.
Trunk (Check) is an awesome tool. I've used it for three months when looking for a decent VSCode extension integrating `actionlint`.

Now I have some repos where everything (linters, formatters, git-hooks) is managed by Trunk for both local dev environments and CI checks through GitHub Actions.

I'd love to apply someday if you start considering remote workers from the EU / UTC timezones.
> Liability still exists in a free market

Only if a wronged party has the resources (time, money, political capital) to pursue it.

Which is but one reason why it is deeply silly to rely on it to make a society go.
> A little scared to make it selectable, as it would make it much easier for spammers/scammers to target locations, as the only verification is email. I do realize they can still change their location that with an emulator.

So there's not really any hurdle at all for automated spammers who can fake their location easily, but you're making it more difficult for genuine users anyway?
Actually if you use the same interface for recommendation systems for content (say RSS feed items, videos, etc.) you get much better results than western content recommenders which don't get accurate negative samples. It finally hit me the reason I didn't understand a lot of the recommender literature is that it doesn't make sense and it's transformative to treat recommendation as a classification problem the way TikTok does. The real Dark Pattern is that YouTube and every other western app looks like

https://marvelpresentssalo.com/wp-content/uploads/2015/09/id...

where you can't conclude anything at all because a user didn't click on an item. (That and the scan-ignore-repeat UI paradigm that has kept RSS readers thoroughly out of the mainstream forever)

Even if you want to have a search-based UI it would still make sense to show you one match at a time and let you thumbs up and thumbs down and have the system remember your choices so you can come back next week and look at new items without the considerable cognitive burden of ignoring. But say “see something once, why see it again?” and people look at you like you’re a psycho killer. The whole advertising economy though is based fundamentally on spamming you with the same crap over and over and a ‘dislike’ button that works (negative sampling) would end it overnight, i guess there’s a reason why you can’t explain something to a person whose paycheck is based on not understanding it.
Politics is, by definition, a deadly struggle of myths, all-against-all. If Sra. Sheinbaum has made her peace with that, then she is not today a scientist, though she may once have been one. If she has not, then failure, immediate and incomprehensible, awaits her. The real point is that no one has any interest in preventing that failure and its associated collateral damage.

I sort of understand their reasoning, then, because acting as a reverse proxy for externally-initiated inbound connections is not typically within the scope of VPN services per se, and especially outside the scope of Mullvad's particular mission of offering VPN services for the purposes of protecting privacy and suppressing censorship.

There are other solutions for your use case, with or without a third-party VPN, that wouldn't require port forwarding. There are also other VPN services that do offer this functionality.
CS degree tells me you've been exposed to concepts at an academic level and maybe even mastered them, but it tells me nothing about hands-on programming skill or how productive you are.

Kind of like an English Literature degree shows that you know a great deal about the language and have read many works but tells me nothing about whether you can write a compelling novel.
I remember first trying out PGP in the early 1990s on a 80386 or 80486 on Linux and it took forever to generate a new key.
I mean. Tinder is pretty awful in general. But the UI does have some merit. It’s exactly the idea of not filling out pages and pages of details about yourself that is great. And likewise, being able in principle to randomly find potential partners that you would not had you gone the route of manually tweaking a bunch of search parameters that your potential partner has to fit.

Swipe UI is not the problem. Tinder is separately awful independently of its UI.
Grew up in national forest, and my grandfather was a logger in the 70s. I remember him and the other old timers complaining the newer PhD's the forest service was bringing in were making dumb excuses for not doing control burn.

I'll never forget my thoughts at the time: "Those PhD's are so smart, surely they are right and these old-timers are just being curmudgeonly"... then years later the forest went up and over 450,000 acres burned, and then not many years later, another roughly 538,000 acres went up.

It was then when I realized how my putting of academia on a pedestal was a major mistake, and then I went and apologized to my grandfather for being dismissive.

My terse summary is that the forest service likes to ship people around, so they aren't in their local forest, so they end up in ecosystems they don't understand as well as the locals but because of their tendency to look down their nose at the locals, they would dismiss knowledge that was trying to be given to them.

I love the forest service, don't get me wrong (much rather have that than BLM!!!) but there are some major flaws in the forest management bureaucracy. To their credit, those fires basically forced change on them because it became too obvious their previous methods were so wrong.

"In 2005, CMS announced requirements for testing of electric-powered wheelchairs as part of efforts to modernize coding (5–7). In this century, CMS, in what might be classified by some as an uncharacteristic move, has provided leadership in evidence-based classification of wheelchairs.

Globally, the International Standards Organization (ISO) manages the wheelchair standards. ISO and the RESNA standards committee work collaboratively. ISO and RESNA have often been driven by outside sources to expedite their work and to address needs of consumers and other organizations. In the 1990s, the European Community Medical Device Directive provided impetus to make a number of changes to ISO standards and to create new standards in response to stricter regulation. The European Committee for Standardization (CEN) went its own direction for a while and over time, CEN and ISO standards have begun to merge. American National Standards Institute (ANSI)/RESNA was a driving force for a long time and often had different standards than ISO. However, this has dwindled in the past decade. Concomitantly, the wheelchair industry has exploded over the past 10 years, and the standards have simply not kept pace. There is a clear and present need for change in standards development and support in the United States.

Most of the participants in wheelchair standards development are employed by the wheelchair industry, an inherent conflict. Unfortunately, wheelchair users and clinicians have traditionally not had the financial support to participate in sufficient numbers. Interestingly, the same companies that participate in the standards committees develop internal tests not represented by ISO or RESNA as part of their product development programs to protect them against legal liability. Test laboratories do the same thing, creating a number of tests that differ from or improve on ISO or RESNA standards. None of the existing standards (ISO, CEN, or RESNA) is comprehensive enough to cover all areas of wheelchair evaluation."

I'm not sure there are relevant units here for most drills. Most drills just have numbers from 1-n regardless of how much torque they can put out. There are calibrated torque drivers out there that can limit to a specific torque, but most hand drills just seem to have a relative measure of torquiness.

> The random number returned is OR-ed with 0b1000000000000001 to set its first and last bit to 1. The last bit set to 1 makes it an odd number and the first bit set to 1 ensures that it is a sufficiently large number which covers the entire range of bits I need.

I can understand setting the low bit to 1 since an even number will never be a prime (edit: obviously except 2). But why set the high bit to 1 as well? Admittedly I don't know much about prime numbers or crypto, but it seems to me like this is just giving up a bit of entropy unnecessarily. What am I missing here?
Assume these same protestors are against Iran for murdering its citizens.
Or Saudi Arabia for killing a million people via famine in Yemen?

Or the muslims killing hundreds of christians in Africa?

Or is it for some reason only the Jews that are getting protested against for killing far less people while trying to stop a terrorist organization embedded in Gaza responsible for the rape, torture and murder of hundreds of Jews.

No antisemitism here at all.

I’ve been looking at buying a new car recently and although I don’t have an appropriate setup at home where I could install a charging point, I’ve wondered around a lot of showrooms and seen quite few EV’s in the process.

I’m seeing EV’s that style-wise just blow the Tesla out of the water, and these are from manufacturers like Kia and Skoda. Meanwhile Tesla produce the cybertruck as their latest offering.

On top of that I personally highly dislike Musk’s politics and his increasing support for why I see as right wing and dangerous politicians (from my perspective as an intersectional minority), so I would also avoid giving him any of my hard earned cash. A couple of years ago I would have jumped at a Tesla. Now I wouldn’t piss on one of it was on fire.
